Among all the scientists of the 1930s, ________ was sosuited to carry out the Manhattan project as J.RobertOppenheimer.
no scientists
not who was a scientist
none
a scientist never he

Answers

Answer:

none

Explanation:

Great question, it is always good to ask away and get rid of any doubts that you may be having.

The above phrase does not have any correct entry. The correct way of stating the sentence would be the following.

"Among all the scientists of the 1930's, none were as suited to carry out the Manhattan Project as J. Robert Oppenheimer."

none is an available answer but since the next part of the sentence says was so it would not make sense or be grammatically correct. Therefore you can either change the available answers or change the next two words in order for the sentence to make sense as well as be grammatically correct.

I hope this answered your question. If you have any more questions feel free to ask away at Brainly.

Among all the scientists of the 1930s, none was so suited to carry out the Manhattan Project as J. Robert Oppenheimer.

System.out.println("x > 9 and y > 8");
else if (z > = 7)
System.out.println("x < = 9 and z > = 7");
else
System.out.println("x < = 9 and z < 7");

Answers

Answer:

no output, it does not print any thing

Explanation:

if-else statement is used to execute the statement after checking the condition if the condition is true, it allows the program to execute the statement otherwise not.

in the code, define the variable with values x = 9, y = 8 and z = 7.

Then, if the statement checks the condition 9 > 9, the condition is false.

So, the program terminates the if statement and executes the next statement but there is no next statement.

the other if-else statement is within the if condition which already terminates.

Therefore, there is no output.

In which of the following is “y” not equal to 5 after execution? X is equal to 4.

a) y = ++x; b) y = x = 5; c) y = 5; d) y = x++;

Answers

Answer:

d) y=x++

Explanation:

In all 3 statements:

y= ++x;

y=x=5;

y=5;

The value of y is equal to 5.

However in the statement y=x++, the value of 5 is equal to value of x prior to the increment operation. The original value of x was 4. So the value of y will be 4. Note that after the statement execution, the value of x will be updated to 5. In effect y=x++ can be visualized as a sequence of following steps:

x=4;

y=x;

x=x+1;

Write a pseudocode statement thatsubtracts the vaiable downPayment from the variable total andassigns the reult to the variable due.

Answers

Answer:

initialize the variables total and downPayment.

int due = total - downPayment;

Explanation:

In the programming, before use the variable in the code you have to declare the variable.

then, there are the mathematical operators in the programming to perform the mathematical calculation.

for perform addition, the operator is '+'.

for performing multiplication, the operator is '*'.

similarly, for performing subtraction, the operator is '-'.

and there is one more assignment operator in programming which is used to assign the value to the variables. The assignment operator is '='.

so,  int due = total - downPayment;

in the above, the program subtracts the downPayment value from the total value and assign to the variable due which is an integer type.

Is recursion ever required to solve a problem? What other approach can you use to solve a problem that is repetitive in nature?

Answers

Answer:

No you can not tell that recursion is ever required to solve a problem.

Recursion is required when in the problem, the solution of the input depends on the solution of the subsets of the input.

Iteration is also another form of repetitive approach we follow to solve that kind of problems.

But the difference between recursion and iteration is :

In recursion we call the function repeatedly to return the result to next level.In iteration certain bunch of instructions in a loop are executed until certain conditions met.

Explanation:

For example in the Fibonacci sequence problem, to find [tex]f_{n}[/tex], we need to compute [tex]f_{n-1}[/tex] and [tex]f_{n-2}[/tex] before that.

In case of recursion we just call the method Fibonacci(n) repeatedly only changing the parameter Fibonacci(n-1), that calculates the value and return it.

                           Fibonacci(n)

                           1. if(n==0 or n==1)

                           2.       return 1.

                           3.else

                           4.      return( Fibonacci(n-1)+Fibonacci(n-1) )

But in case of iteration we run a loop for i=2 to n, within which we add the value of current [tex]f_{i-1}[/tex] and [tex]f_{i-2}[/tex] to find the value of [tex]f_{i}[/tex]

                           Fibonacci(n)

                           1. if(n<=2)

                           2.    result = 1

                           3.     else

                           4. result1 =1 and result2=1.

                           5.      {  result = result1 +result2.

                           6.         result1= result2.

                           7.         result2 = result.

                           8.      }

                           9.  output result.

When applying strict “Private access” level to a component. Which services should the designer provide in its class to allow the object to communicate with the outside world? What should be the access level of these services?

Answers

Answer:

public accessor methods

Explanation:

When applying strict “Private access” level to a component the designer should provide public accessor methods in its class to allow the object to communicate with the outside world. The access level of these services must be public so that they can be accessed by other classes and objects of the outside world.

Below is an example of such a class design in java :-

class MyClass {

private int num; //private class component

 

public int getNum(){ //public accessor method to allow the object to        communicate with the outside world

 return num;

}

}

Is bit stuffing necessary in the control or address field in theHDLC protocol? why?

Answers

Answer:

Many network and communication protocols require bit stuffing for the following purposes: to avoid the interpretation of data as control information. For example, with six consecutive 1 bits, X.25 uses the bit stuffing,signal the beginning and end of a frame.

High-level Data link control (HDLC) is a bit-oriented protocol for point-to-point and multi-point communication.P/F bits are present in HDLC control field.

So,Yes bit stuffing is necessary in control field.

Glven an array named Scores with 25 elements, what is the correct way to assign the 25th element to myScore? A. myScores + 25 B. myScore Scores[24] C. myScore Scores[25) D. myScore== Score[last]

Answers

Answer:

myScore Scores[24]

Explanation:

The array is used to store the data in continuous memory location.

The index of array start from zero, it means first element store in the index zero and second element store in the index 1. So, the index at which the element store is less than 1 from the number of element.

so, the last element is 25 - 1=24.

Option A: myScores + 25

It is not the correct way to store the element.

Option B: myScore Scores[24]

it is the correct form and also the index location is correct.

Option C: myScore Scores[25)

index number is wrong and also the bracket is wrong, it must be [ ].

Option D: myScore== Score[last]

It is not the correct way to store the element.

There, the correct option is B.

      }

      cout<<"Enter an operation(+,-,*,/), Q to quit: ";

      cin>>opt;

  }

  return 0;

}

Explanation:

First, include the library iostream, it allows to use the input/output instruction.

Create the main function and declare the variables.

Then print the message on the screen using cout instruction.

cin instruction is used to store the value into the variable.

then, take a while and check the condition if the value enters by the user is 'Q' or not. if true then enter the while otherwise exit.

after that, store the number enter by the user in the variables and then take the if-else statement for matching the operation enter by the user if match true then do the match operation.

This process continues until the user enters the value 'Q'.

if the user enters the 'Q'  then condition false and exit the program.

while (n > 0) {
System.out.print(message);
n--;
}
}
Please explain so that I can learn from you.

Answers

Answer:

aaaa

Explanation:

We have a function nPrint which return type is void, it means it returns nothing.

we declare the two parameters, one parameter is string type and the second parameter is an integer type.

Then, it has a while loop that executes the statement again and again until the condition not FALSE.

Let dry run the code:

First, call the function nPrint("a", 4) bypassing the value in the argument.

then, the value receives by the parameters, the message contains "a" and n contain 4. After that, while loop checks the condition 4 > 0, which is TRUE and the program starts executing the statement.

The program prints the message on the screen "a" and then decreases the value of n by 1. So, the value of n becomes 3.

The above process repeats for the value of n = 3, 2, 1

and print the message "aaaa".

then, the condition becomes false and the program terminates the loop.

Therefore, the answer is aaaa

Write the 8-bit signed-magnitude, two's complement, and ones' complement representations for each decimal number: +25, + 120, + 82, -42, -111.

Answers

Answer:

Let's convert the decimals into signed 8-bit binary numbers.

As we need to find the 8-bit magnitude, so write the powers at each bit.

      Sign -bit 64 32 16 8 4 2 1

+25 - 0 0 0 1 1 0 0 1

+120- 0 1 1 1 1 0 0 0

+82 - 0 1 0 1 0 0 1       0

-42 - 1 0 1 0 1 0 1 0

-111 - 1 1 1 0 1 1 1 1

One’s Complements:  

+25 (00011001) – 11100110

+120(01111000) - 10000111

+82(01010010) - 10101101

-42(10101010) - 01010101

-111(11101111)- 00010000

Two’s Complements:  

+25 (00011001) – 11100110+1 = 11100111

+120(01111000) – 10000111+1 = 10001000

+82(01010010) – 10101101+1= 10101110

-42(10101010) – 01010101+1= 01010110

-111(11101111)- 00010000+1= 00010001

Explanation:

To find the 8-bit signed magnitude follow this process:

For +120

put 0 at Sign-bit as there is plus sign before 120. Put 1 at the largest power of 2 near to 120 and less than 120, so put 1 at 64. Subtract 64 from 120, i.e. 120-64 = 56. Then put 1 at 32, as it is the nearest power of 2 of 56. Then 56-32=24. Then put 1 at 16 and 24-16 = 8. Now put 1 at 8. 8-8 = 0, so put 0 at all rest places.

To find one’s complement of a number 00011001, find 11111111 – 00011001 or put 0 in place each 1 and 1 in place of each 0., i.e., 11100110.

Now to find Two’s complement of a number, just do binary addition of the number with 1.

Final answer:

The question involves converting decimal numbers to 8-bit signed-magnitude, two's complement, and ones' complement binary representations. Positive numbers are the same in all three representations, whereas negative numbers differ. The most significant bit represents the sign in signed-magnitude, while two's and ones' complements involve bit inversion for negative numbers.

Explanation:

The question involves converting decimal numbers into three different binary number representations: 8-bit signed-magnitude, two's complement, and ones' complement. These representations are used in computing to express positive and negative integer values. For an 8-bit system, the most significant bit (MSB) indicates the sign of the number, where '0' usually represents positive and '1' represents negative.

For +25, the 8-bit signed-magnitude is 00011001, the two's complement and ones' complement are also 00011001 since it is a positive number.

For +120, the 8-bit signed-magnitude is 01111000, the two's complement and ones' complement are also 01111000.

For +82, the 8-bit signed-magnitude is 01010010, the two's complement and ones' complement are also 01010010.

For -42, the 8-bit signed-magnitude is 10101010, the two's complement is 11010110, and the ones' complement is 11010101.

For -111, the 8-bit signed-magnitude is 10101111, the two's complement is 10010001, and the ones' complement is 10010000.

Note that the two's complement is found by inverting all the bits of the absolute value of the number and then adding 1 to the least significant bit (LSB). The ones' complement is found simply by inverting all bits of the absolute value of the number.

When displaying fonts, what%u2019s the difference between pixels, points and ems?

Answers

Answer:

All 3 are CSS unit sizes which we can use for margins, fonts, borders etc.

Explanation:

CSS has four different unit sizes. These are:

Pixels (px)

Points (pt)

Ems (em)

Percentages(%)

These units are divided into two different groups. They are fixed and relative.

Pixels and points are fixed , whereas em and percentages are relative unit sizes. Relative unit sizes are good when creating scalable layouts.

Ems (em):

An em is a CSS unit that measures the size of a font. Originally, the em was equal to the width of the capital letter M, which is where its name originated.

It stands for "emphemeral unit" which is relative to the current font size.

The "em" is a scalable unit that  is used in web document media. Ems have mobile-device-friendly nature.

Pixels (px):

Pixels are fixed-size units that are used in screen media. One pixel is equal to one dot in computer. The problem with pixel unit is that it is not relative .

Points (pt):

Point values are only for print. A point is a unit of measurement use for real-life ink on paper. Generally, 72pts= 1 inch which is one real-life inch like on  a ruler. Point  is not recommended to use in web pages.

Generally, 1em=16px=12pt=100% if the body size is 100%.

Relative unit sized fonts change and fixed unit sized fonts remain the same.

For example,

body { font-size: 100%}

p{font-size: 16px}

Explanation:

For each iteration the line number 11 or line number 15 will be executed.

Both lines, cut the array size to half of it and takes as the input for next iteration.
